Orca Wetsuit Size Chart The Predator wetsuit is perfect for the swimmer looking for the ultimate swim assistance. It's designed with extended 0.88Free technology for the ultimate feeling of freedom and an even higher level of buoyancy to keep you streamlined even when you tire. The highly flexible nylon fabric provides unparalleled freedom of movement. Features: - 0.88 Free Material Technology: Used on the sleeves, underarms and now upper back of the Predator make it feel like you're not even wearing a wetsuit - with total freedom throughout every phase of your stroke. Titanium coating on this super flexible material provides thermal protection for your arms to regulate your temperature - Exolift with Aerodome: The unique sandwiching of Exo-Lift technology and the super buoyant Aerodome neoprene on the lower front and back of the suit provides the ultimate lift where it's most needed. These panels have no lining and so don't absorb water and so the level of buoyancy offered remains unchanged no matter how long you've been in the water - Core Lateral Stabilizer: Using a less flexible material on the core panels to stabilize the body. The suit feels stiff but once in the water it gives the feeling of swimming on a surfboard - greatly improving your body position and so also your speed - 44Cell: Orca uses 1.5mm panels of Yamamoto 44cell neoprene in the key underarm area of the Predator to compliment the super stretchy 0.88 Free arms-providing you with a wetsuit swimming experience never felt before - HydroLite Panels: Make transition that extra bit faster using the super fast SCS (Nano ICE in the Predator) which combined with a special lining which absorbs less water to improve buoyancy while also being extremely sleek -making the suit fast to remove in transition saving you precious seconds - Nano Ice: Offers even lower drag co-efficient, ensuring the fastest swim possible. The underwater co-efficient of dynamic friction of the Nano SCS is 0.026 in comparison to 4.0 of regular neoprene. Less friction = more speed! Nano ICE is the latest upgrade to Nano SCS - InfinitySkin Lining: It plays an integral part in the unbelievable flexibility of Orca's top end wetsuits. Constructed from a high stretch nylon, InfinitySkin is strategically placed where ultimate stretch is required and allows the wetsuit to move dynamically through your swim stroke - Aerodome 2: Beneath the dimpled surface of Orca's Aerodome 39-cell neoprene are hundreds of air cavities, which provide 30% more buoyancy than normal 5mm neoprene. Aerodome panels are strategically placed around the heaviest parts of the body, lifting you into the optimum swimming position. Aerodome 2 is an upgrade that uses a new lining to increase flexibility and comfort
